The research programme on nematodes continues to be highly productive and relevant. The research projects below include plant parasitic nematodes and entomopathogenic nematodes. A number of projects also involve research on entomopathogenic fungi. The use of both fungi and nematodes in conjunction as biological control agents against a range of insects is an exciting prospect. The research will allow for enhanced biological control of orchard pests and better integrated management in orchards in the future.
